Air Filtration System

Filtration sections can be manufactured that contain pleated, bag, and HEPA filter options.

Humidifiers also can reduce static electricity in the air. Baikal builds humidifier sections that are provided with sloped drain pans. These sloped drain pans prevent the added moisture from going onto the floor.

Our humidifier sections are constructed using aluminum extrusion and 2” double wall panels. The panels are insulated with 3 lb density fiberglass.

‘Home is where the heart is,’ as the saying goes, though yours might just start racing when you learn the truth about household air contaminants. According to the EPA, indoor spaces are often 2 to 5 times more polluted than outdoors, sometimes as much as 100.
Air filtration systems work tirelessly to eliminate the countless toxins free in the air, though not all of them work exactly the same way. Nevertheless, air filtration systems are becoming more and more common as people realise the importance of truly fresh air.


How much does an Air Filtration System cost?

The total cost of a commercial air filtration depends greatly on the specific configuration as well as the level of filtration. Whole-house configurations vary from around $400 to $4,000 USD, whereas portable units are cheaper but limited in scope. For whole-house systems, here’s what you can expect:

  • Extended Media Filter: $400 to $600 
  • Electronic Filter: $500 to $1,500 
  • HEPA filters (link): $1,500 to $4,000
  • Portable Air Purifier: $500 to $1,800

Despite the expense of an air filtration system, they are a solid investment. As you’d expect, there are various health benefits to reducing levels of impurities in a household or workplace.

Air Filtration System: The Basics

To many, home is a sanctuary; a reprieve from the many worries in the outside world. It is where you can breathe a big sigh of relief after a long day outside. However, breathing inside the home can be more dangerous than breathing outside the home. In fact, many experts believe that indoor air can be five times as polluted as outdoor air.

But what if there is a device that is specifically designed to clean the air inside your house, get rid of contaminants such as smoke, dust, odors, and other particles? Would you want that device? Of course, you would!

Why Every Home Needs an Air Filtration System

The health as well as the comfort of a building’s occupant relies on the quality of the structure’s indoor air. Many contaminants and pollutants are trapped indoors; especially for newer structures where the seals are tighter.

Indoor air pollution is a legitimate cause for concern. In fact, the Environmental Protection Agency puts it on the top five on its list of environmental dangers to the public. This is why a home or a building structure needs an air filtration system.

Air filtration works by trapping and capturing pollutants and other particles so the air that is pushed back into the space is clean and contaminant-free.

Air Filtration System; Defined

Air filtration is the technology that is used in residential, commercial, and industrial spaces to remove contaminants from an airstream.

The air filtration unit a part of the larger air purification system designed to pull dirty air from inside the home, capture and trap pollutants, cleanse the air, and circulate the clean air back into the indoor space.

A good air filter must:

  • assure adequate ventilation;
  • be able to filter out a wide range of small particle sizes, and;
  • be reasonably cost- and time-effective maintenance schedules to avoid adverse effects on ventilation and efficiency.

Many homeowners and renters invest in a whole house air filtration system; and for good reason. The main purpose of a home air filtration system is to remove dust particles, pet dander, dust mites, and other pollutants from the air you breathe. Good ventilation can also help get rid of some contaminants, but good home air filters can make all the difference in the world as they improve the quality of air as well as the health and comfort of all of the home’s occupants.

How the Air Filtration System for Home Works

Humans need air to breathe. The good news is we know what is in the air, as in all the particles. The better news is that we understand if these particles are good or bad for us. Perhaps the best news, though, is we have also found a way to purify the air we breathe. Pure air filtration is a miracle of modern science.

So, how exactly does an air filtration system work?

Many people think that air filters are extremely tiny versions of a net whose job is to create a blockade for large particles. There is some truth to this; but it is important to understand that there are different kinds of filters. However, regardless of the kind of filter, the job of home air filtration remains the same: they make narrow and intricate pathways for the air while capturing and trapping everything else.

Very basically, here is the three-step process of the entire air purification system:

  1. The air purifier’s fans suck the air from an indoor space and passes them through the filters.
  2. The filters capture and trap the contaminants in the air.
  3. The fans blow the newly cleaned air back into the indoor space.

Air filters are usually part of a home’s heating and/or cooling system. There are three ways air filtration products work based on the size of the particles.

  1. Large particles – When large particles try to pass though the filters, they are physically blocked. This process is called sieving.
  2. Small particles – Small particles are harder to block directly so they are diffused and scattered around the filter until they eventually collide and get caught on the filter’s fibers.
  3. Medium particles – When medium particles pass through the filter, they are grabbed in a process called interception.

What’s In It For You: The Health Benefits of an Air Filtration System

Home air filters offer a lot of health benefits by capturing and trapping potentially harmful contaminants. Multiple scientific studies have proven that they help improve respiratory health and have positive impacts on cardiovascular health. How? The following are just a few of the advantages of having a whole home air filtration system.

  • Removes asthma triggers (I.e. dirt, dust, dry skin cells, carbon monoxide, air-freshening sprays, fumes from household cleaning products, paint products, smoke from cooking, particles from cosmetics, perfumes, hairsprays, etc.)
  • Removes allergy triggers (I.e. dust, animal dander, pollen, smoke, etc.)
  • Traps smoke from tobacco and cigarette
  • Traps airborne asbestos particles
  • Eliminates Radon gas which is cancer-causing gas
  • Prevents outside fumes and pollutants from getting indoors
  • Reduces carbon dioxide levels in the home
  • Eliminates Volatile Organic Compounds (VOC)

Indoor air pollution is a very real thing. The air inside your home can be laden with a complex mixture of contaminants coming indoors from outdoor air and those that are generated by indoor sources. The deterioration of the ambient air leads to the deterioration of health. Therefore, advanced air filtration systems are a necessary investment for every home.


What is an Air Filtration System?

Air filtration is simply the removal of contaminants from an airstream, thus an air filtration system is the specific gear used to do such. Specifically designed to draw in ambient air, filter out harmful particles, and recirculate the treated air, these systems can be found in all manner of residential, commercial and industrial spaces.

How does an Air Filtration System Work?

If you want to understand how air filtration systems work, there a few terms to cover:

  • Straining/Sieving: Almost all filters rely on a membrane, the pore size of which allows air to pass but blocks particles. This kind of filtration depends on the physical size of particles, where it best deals with large particles.
  • Interception: Rather than simply getting stuck in the membrane, interception is where particles actually attach to filter fibres, which is often necessary when dealing with those of a medium size.
  • Diffusion: as particles travel, they are naturally attracted to areas of lower concentration. Filter manufacturers manipulate this by designing membranes that encourage such behaviour, great for catching smaller particles in the filter fibres. 

In any case, an air filtration system works by creating a tangle of pathways that particles find incredibly difficult to navigate through. Meanwhile, air passes through unimpeded, ensuring proper ventilation.

What Contaminants does an Air Filtration System remove?

The efficiency of an air filtration system relies on the particular kind of filter technology employed, where high-efficiency particulate absorbing (HEPA) filters (Link to HEPA article) are considered the best protection against trickier contaminants. 

There are lots of impurities caught by an air filtration system, including:

  • Allergens: dust, dander, pollen, mould spores, etc.
  • Asthma Triggers: cosmetics, cleaning products, sprays, fumes, smoke, etc.
  • Pathogens: bacteria, viruses, fungi, microbes, etc.
  • Chemical Contaminants: radon gas, VOCs, carbon dioxide, outdoor fumes, etc. 

Air filtration systems use additional purifying filters to eliminate the above contaminants, which may include electrostatic, ionising and carbon examples. 

What is a Pure Air Filtration System?

Though also responsible for cleaning the air within an indoor space, a pure air filtration system makes use of more advanced technology, such as ultraviolet light and needlepoint bi-polar ionisation. These methods can neutralise DNA-based airborne contaminants like bacteria, viruses, and mould spores.

Pure air filtration systems can be whole-house, where they’re integrated into the existing HVAC design, or appear as portable stand-alone units for single rooms. The former is the best way to ensure high air quality throughout the residential or commercial space, whilst the latter is a great solution for isolated areas with high levels of contamination. 

Contaminated ambient air negatively impacts health in a multitude of ways, most alarmingly various respiratory and cardiovascular diseases. Although a standard ventilation system may remove some airborne contaminants, you will likely notice a huge improvement in air quality by installing whole-house air filtration, making it an investment that every homeowner should seriously consider.
